Hi guys! just tried your game :) for being your first game jam it is not bad at all! I liked the concept of crafting the weapons so that you know how to fight the boss in the final level. I would make the boss' weak points more visual because I thought I needed to hit the boss anywhere until I found the hint you left in the level.
Anyway, very fun game. Great job guys! Please feel free to try our game as well and leave feedback :)
